20 Then Aaron’s sister Miriam, who was a prophetess, took a tambourine in her hand. All the women followed her, playing tambourines and dancing.
21 Miriam told them:“Sing to the Lordbecause he is worthy of great honor.He has thrown the horse and its riderinto the sea.”
22 Moses led the people of Israel away from the Red Sea. The people went into the Desert of Shur. They traveled for three days in the desert but found no water.
23 Then they came to Marah, where there was water. But they could not drink it because it was too bitter. That is why the place was named Marah.
24 The people grumbled to Moses. They asked, “What will we drink?”
25 Moses cried out to the Lord. So the Lord showed him a tree. Moses threw the tree into the water. And the water became good to drink.There the Lord gave the people a rule and a law to live by. There he also tested their loyalty to him.
